PTrace Commands

The PTrace commands provide options for selecting trace records for display, so you

can suppress those records that do not relate to the problem you are investigating. The

PTrace commands also provide options for specifying the way in which the trace

records are formatted.

Although PTrace provides a common set of commands for displaying trace records, not

all of the PTrace commands are supported by each subsystem. This is because of the

structure of the PTrace code. The PTrace code actually consists of two modules. The

first module contains the code shared by all subsystems; the second contains the

additional, subsystem-specific code that actually displays the PTrace records. Thus,

those commands implemented by the first PTrace module are supported by all

subsystems: ALLOW, COUNT, ENV, EXIT, FC, FIND, FROM, HELP, LIMIT, LOG,

NEXT, OBEY, OUT, PAGESIZE, RECORD, and RESET. Those additional commands

implemented by the subsystem-specific PTrace modules vary from subsystem to

subsystem. Of the commands that fall into the subsystem-dependent category, the

NonStop TCP/IP subsystem supports the following:

DETAIL

HEX

LABEL

OCTAL

SELECT

TEXT

The HEX, OCTAL, and TEXT commands are implemented in the standard manner.

The LABEL and SELECT commands vary slightly from the standard, as described later

in this section.

The following subsystem-dependent commands are not supported:

EBCDIC

FILTER

SETTRANSLATE

TEST

TRANSLATE

Table 4-7 lists and describes all the PTrace commands supported by the NonStop

TCP/IP subsystem.
